Fuel Level Sensor

The fuel level sensor is attached to the fuel pump assembly, and consists of a variable resistor controlled by the level of an attached float in the fuel tank. When the fuel is low, resistance in the fuel level sensor is low (16-34 ohms) and the number of illuminated bars on the fuel gauge is minimal (0-2 bars illuminated). When the fuel level is high (100-155 ohms), the resistance in the fuel level sensor is high and the number of illuminated bars on the fuel gauge is greater (9-11 bars illuminated).
